Rakhman'ko, V. Zhilko, V. Egorov] A method was proposed for the photometric determination of carboxylic acid impurities in polyvinylchloride, food and machine oils, and other samples. The method is based on the interaction of the acid groups of the sample with the ion pair of Bromothymol Blue and the trinonyloctadecylammonium cation in the binary solvent toluene-tetrahydrofuran. The method is highly sensitive and reproducible and was tested with many samples. MAIK "Nauka/Interperiodica”, 2005 Rakhman'ko E. Department of Chemistry, Belarussian State University, ul.
